Kuling, province of Kiangsi. Lat. about 29.y-. Alt. 2500-3500 feet. 

 July 9, 1917. (L. H. Bailey, Sedum no. 2.) 



A very interesting little plant, closely related to the species constituting 

 the InvolucrcUa group of Maximowicz, of which 6'. &puriuin M. Bieb. and 

 *S'. sloloniferum S. T. Gmel. are the best-known species, and which, as hitherto 

 icnown, was confined to the Caucasus and Asia Minor. It has tlie broad 

 opposite leaves and red flowers which characterize the group. Its elongate 

 semi-erect petals come close to those of >S. spiirium ; and its most unusual 

 feature, the epigeous or slightly subterranean stolon-like barren shoots, is 

 in Sedum found very seldom — in two species of the Involiicrata group and in 

 one of the Telephium section. As regards the former, the shoots of S. Listoniac 

 Visiani are above, and those of S. proponticii'm Azuavour below ground. In 

 both these species the barren shoots are short and congested, while in the 

 present plant tliey have relatively long internodes. Both agree with S. Baileyi 

 in having erect annual flowering shoots. In iS'. cauticolum Pi'aeger (the 

 Tehphium referred to), a Japanese plant, the shoots are subterranean and 

 very slender, as in 8. Baileyi. A few of tiie RhocUola section, notably -S'. cras- 

 sipes, can on occasion produce similar underground stoloniferous shoots, but 

 this is abnormal.
